Solve -1/2+1/10

$$\frac { - 1 } { 2 } + \frac { 1 } { 10 }$$

Evaluate

$$-\frac{2}{5}=-0.4$$

Solution Steps

Fraction \frac{-1}{2} can be rewritten as -\frac{1}{2} by extracting the negative sign.

$$-\frac{1}{2}+\frac{1}{10}$$

Least common multiple of 2 and 10 is 10. Convert -\frac{1}{2} and \frac{1}{10} to fractions with denominator 10.

$$-\frac{5}{10}+\frac{1}{10}$$

Since -\frac{5}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{-5+1}{10}$$

Add -5 and 1 to get -4.

$$\frac{-4}{10}$$

Reduce the fraction \frac{-4}{10} to lowest terms by extracting and canceling out 2.

$$-\frac{2}{5}$$

Factor

$$-\frac{2}{5} = -0.4$$
